18 Claims.

This invention relates generally to display binders and more particularly to binders of the type used by salesmen and others for displaying in a neat and attractive manner pictures, data, and other matter forming a part of the presentation.

The object and general nature of this invention is the provision of new and improved means for displaying one sheet above the other so as to provide what is called a double page spread, that is, the picture or otherpresentation is of such size as to require two sheets for its display. In this connection it is a feature of this invention to provide a display binder of the type that can be folded into a compact book form but which may be extended for display purposes to hold one set of sheets above the other but in substantially coplanar relation, thus making it possible to display relatively large charts, pictures, maps, and other subject matter without requiring a binder of excessively large size.

A further feature of this invention is the provision of a display binder having a folding easel associated with the front and back covers so that the binder may be folded into'compact book form to facilitate carrying the same and may be erected for display merely by turning back the front cover and unfolding the easel, thereby setting up the binder so that the front cover and easel support the sheets in extended relation one above the other, the binder being conveniently and quickly folded back to its compact book form merely by closing the front and rear covers over the sheets, this action automatically folding up the easel.

More specifically, a feature of this invention is the provision of a cover carrying mechanical wire bound or ring or arch-connected sheets so that the latter are protected from wear when not set up for display, in connection with means co operating with the cover and reacting against the sheet binding means for quickly and conveniently setting up the sheets, one sheet above the other, for visual presentation and demonstrating purposes.

. Another feature of this invention is the provision of a binder having sheet binding means of the mechanical type in which the joint or connection from which the individual sheet-holding rings extend is disposed in a concealed position between two panels of the binder so as not to interfere with the leaves, no matter to what position the binder is turned.

These and other objects and advantages of the present invention will be apparent to those skilled in the art after a consideration of the following detailed description taken in conjunction with the accompanying drawings.

Figures 12, 13, 14, and 15 are sections showing the manner of assembling the binder; and Figure 16 is a fragmentary view ofthe rigid reenforcing sheet employed in the binder shown in Figures 10 to 15, inclusive.

Referring now to the drawings, the form of the display binder embodying the principles of the present invention as shown in Figures 1 to 4 comprises a cover indicated in its entirety by the reference numeral I, an easel section 2, suitable sheet binding means 3, and a set of superimposed separate sheets 4 having perforations 5 (Figure 1) punched therein along the inner edges.

The cover I consists of a front cover member 2 'l and a back cover member 8, each of which includes a rigid board 9 bound, as at ID, in cloth, imitation leather, or other material, as desired. The cover binding l preferably is continuous and extends from one cover member to the other. Generally centrally thereof the cover members i and 8 are spaced apart and the material Hl arranged to form a flexible portion indicated at l I. This flexible portion serves as a hinge and permitsthe covers to be folded together, as in Figures 2 and 3, or turned back one on the other, as indicated in Figure 1. Also, the flexible section II is of sufiicient extent to embrace and enclose the sheet binding means 3. The front cover 7 also includes a relatively heavy sheet E of fiber board or other material glued to the inner side of the board 9, as best indicated in Figure 3. Preferably, the sheet l5 overlaps the edge portions of the fabric or other material H), as indicated at It, whichis the usual practice.

The easel 2 comprises two panels I 3 and 20 and a foldable connecting panel section 2|, as best indicated in Figures 1 and 3. The sections I9, 28, and 2! are connected together to form a sheet or strip which is folded at the points 22, 23, and 24, the inner panel l9 being appreciably heavier than the outer panel 20 since the panel I9 is required to support a certain portion of the weight of the cover and the sheets 4, as will be described below. The folded section or stub 23 (Figures ,1 and 3) of the easel 2 is permanently secured, as by rivets 26 or the like, to the outer edge of the back cover 8 so that when the latter is swung away from the panel [9, the easel 2 is extended, as indicated in Figure 1, and the sheets 4 are supported by the panel l9. Thus, broadly considered, the parts 1 and 19 form rigid backs for the binder or bookand the part 8 serves as a strut to hold the parts 1 and I9 in extended relation.

The connecting panel 2! preferably is creased orscored at the fold line 24 in such manner that when closing the binder the two parts of the section 2! tend in and of themselves to fold in wardly without requiring that they be moved manually. Thus, when extended for display purposes, as in Figure 1, by simply lifting the device by the cover 1, or by turning the cover 1 down over the lower sheets 4 or the part l9 and then grasping the covers 1 and 8, the parts 8, I 9, 20, and 2| fold together as shown in Figure 3.

The sheet binding means, indicated in its entirety by the reference numeral 3, may be of any suitable character, but preferably it is constructed so that the sheets 4 may be turned freely one at atime from one side of the binder to the other.

For example, the binding means 3 may be one of the mechanical or wire bound types known in the industry as Spiral, Wire-O, Cercla, Coil, etc., and by way of illustration only I have shown the sheets 4 as carried by binding of the Wire-O type, best shown in Figures 4 and 5, which is in the form of a wire 33 having ring-like arches or loops 34, each of which consists of a pair of generally arcuate sections 35 and 36 connected by a short rounded end loop 31, the adjacent sections 35 and 36, respectively, of contiguous arches 34 being connected by a longer loop 38, the loops 38 thus serving as means connecting the adjacent ends of the arches 34 while the ends 3'! are free and, inassembly, are pressed into the perforations 5 to connect the sheets 4 in assembled relation. The connecting sections 38 in this form are arranged to lie between the panels l5-and 20 when the binder is ,extended, as best shown in Figure 4, since these parts separate when the binder is closed, as shown in Figure 3, but the sections 38 may be otherwise disposed if desired or required. The panels I5, 19, and 20 are also punched to receive the binding parts 34, this being most conveniently done when the latter are inserted in the sheets 4 and before the panel I5 is glued to the front cover I and before the stub 23 is riveted to the outer edge of the back cover 8. In fastening the panel to the inside of the front cover the panel 15 is secured in place to make available the maximum amount of the parts 34 to receive the sheets 4, as best shown in Figure 4.

While I have described a particular kind of binding means for the sheets 4, it is to be understood that this is for illustration only and that this invention is not necessarily limited to any particular binding means, as will appear from the description below of other forms of this invention. It will also be understood that where economies are desirable, the'sheets and panels may consist of or be formed from any suitable grade of board or paper stock, as desired. Figures 8 and 10, described below, show two of such forms. The operation of the display binder described above is substantially as follows: The salesman or other user ordinarily carries the binder about in the position shown in Figure -2, namely, folded into compact book form. When it is desired to set up the binder for display, the user merely swings the front cover I! back until it rests against the inner edge of the back cover 8, at the point indicated by the reference numeral 32 in Figures 1 and 4, this movement being accommodated by the flexible cover section H. The front panel I9 is then moved forward to set up the easel 2, which extends the section 2!, and the parts take the position shown in Figure 1, the upper cover 7 and the panel l9 thus serving as backs for the leaves 4. In practice, the opening of the binder for display purposes can be made with one movement. The opening movement of the front cover "I causes the latter to move relative to the arches 34 to a position substantially underneath them, as indicated in Figure 4, and closely adjacent to the inner edges of the easel panels ['9 and 2D. The connecting section H of the easel limits the outward or spreading movement of the panels I!) and 2G, and the panel serves as a tension member reacting against the part of the binding means 3 against which the inner edge of the upper cover member 7 bears to determine the angle at which the parts are supported. The connecting panel 2! is so designed that when the front cover i rests against the upper edge of the back cover 8 and the easel 2 is extended, the cover I and the heavier panel IQ of the easel 2 are supported in substantially coplanar relation, as indicated in Figure 4, whereby the sheets 4 are supported one above the other in edge to edge relation and also substantially in the same plane. The weight of the upper sheets and the front cover l is supported by the front cover 7 resting against the inner or upper edge of the back cover 8 and reacting at its inner edge against the binding means- 3 which, in turn, is held in position by the inner edges of the easel panels l9 and 26, the binding 3 bearing down on the panel I9, and'hence the latter is preferably a rigid member, and pulling up on the tension panel 20.

When returning the binder to its closed position (Figure 2) all that it is necessary to do is to lift the binder and the easel will automatically fold .up between .the back cover and the sheets by virtue of the creasing or scoring 24 of the connecting section 2|, while the covers 1 and 8 will close over the binding 3 and sheets 4, as shown in Figure 3. Thus, like the opening operation, the closing of the binder can be done with one continuous operation.

..It will be noted from the above description that the sheets are supported in compact form and that the front and back covers 1 and .8 protect the sheets while the flexible connecting section I I of the covers encloses and protects the binding 3. Yet it is the work of only a moment to open the display binder and set the same up with the sheets disposed in generally upright position to facilitate a presentation of the material printed or carried thereon. The setting up .of the display binder is thus accomplished without the moving, adjusting, or snapping of any mechanical devices, the closing of the .display binder being effected in the same manner. It will also be seen that when the binder is closed there is no operating mechanism or sheet binding exposed. The method of manufacturing is simple, since the two covers with their binding, which forms the flexible connecting means between the covers, are entirely separate from the folding easel, which consists of sections bound or hinged to form one continuous easel. The punching of the easel panels and the panel l5 that is glued to the cover is best effected when thesheets are punched. Thus, the final assembly of the unit requires only that the fold 23 of the easel be riveted to the back cover and the panel l5 glued to the front cover.

Mechanical binding means of the type described above produces a compact assemblage but does not as readily accommodate the exchange or replacement of single sheetsas binders of the loose leaf type. Figures 6 and '7 illustrate the principles of the present invention as embodied in a loose leaf binder 44 having cover members 45 and 46 connected together by a flexible section 4'! that is preferably formed by spacing apart the cover boards 49 and 50 and connecting them by the binding material 5| which may be leather, imitation leather, fabric, or. any other suitable material. In the more economical forms, the parts 45, 46, and 41 may be of paper or board stock. Loose leaf metal 53, consisting of a backbone 54 and hinged arches 55 having straight sides 56 and 51, is rigidly fixed to the cover member 45 adjacent its inner edge by any suitable means, such as rivets 58.

The binder 44 includes an easel unit 62 which consists of a rigid panel 63, a tension panel 64, and a connecting panel 65 creased or scored, as

at 66, to fold inwardly, as in the form of the in- The panels 63, 64,

vention described above. and 65 are connected at fold lines 61 and 68, the latter portion forming a stub II which is fastened, as by rivets 12 or any other suitable means, to the outer edge of the other cover member 46. The panel 63 preferably is of heavier stock than the other panel since it is required to be sufficiently rigid to cooperate with the other parts to hold the binder in display position. The inner edges of the panels 63 and 64 are perforated to receive the arches 55 of the loose leaf metal 53, and the inner edge 64a of the panel 64 is constructed to be strong but flexible, as will be clear from Figure 6. The sheets or leaves carried by the arches 55 are indicated at 14.

The opening and closing movements of the binder 44 aresubstantially the same as the binder shownin Figures 1 to 4. When the binder is closed the easel 62 folds in between the sheets 14 and the cover member 46, both easel panels 63 and 64 lying on the side of the sheets 14 opposite the base or backbone 54.

. The binder is arranged for display position by opening the covers as in an ordinary binder, and then grasping the cover member 45 and lifting the binder to permit the cover member 46 to be swung back against the upper cover member 45 to support the latter and the unfolding of the easel panels 63, 64, and 65, the latter determining the angle between the easel panels. It will be noted that in this action the inner edges of the easel panels .63 and .64 move relative to the rings from, the straight sides 56 of the arches (Figure 7) to the other straight sides 51. The panel 64 acts in tension against the binding rings 55 of the loose leaf metal. 53, which is rigidly secured to the cover member 45, and determines the angular position the cover member 45 takes relative to the other cover member 46 when the binder is extended for display, as shown in Figure 6. As in the form of the invention shown in Figures 1 to 4, the easel panels 64 and 66 are so designed that when the binder is in display position the rigid cover member 45 and the rigid easel panel 63 are in substantially coplanar relationship. It will also be noted that in this form of the invention the sheets 14 are supported upon the straight portions of the arches 55, both when the sheets are in their lower position or in their upper position. The support of the sheets for display on the straight portions of the arches 55 is an advantage inthat the sheets are maintained in the proper position at all times. When the binder is supported for display, it will be seen that the upper cover member 45, together with any sheets lying against it, bears downwardly through the loose leaf metal 53 against the rigid easel panel 63 and backwardly against the rigid cover member 46, the angular movement of the upper cover member 45 being determined by the effective length of the easel panel 64.-

Mention was made above to the fact that the principles of this invention might well be embodied in an economical form of binder in which the covers are made from cardboard or the like. Referring now more particularly to Figure 8, the reference numeral 36 indicates in its entirety a binder having covers 8! and 82 formed of relatively inexpensive paper orboard stock connected together by a flexible cloth section 83 glued .to the covers. Loose leaf metal 85, which includes divided rings 85 hinged to a support or backbone 81, is fastened to the cover 8! by rivets connecting the backbone 81 to the edge of the cover St-at or adjacent the portion to which the flexible section 83 is glued. The loose leaf ring metal 35 is of conventional construction and supports a plurality of sheets 89.

The easel portion 9! of the binder shown in Figures 8 and 9 includes a strip of paper stock of suitable Weight having sections'93 and 94 connected to a rigid section 95, which may, if desired; be formed by an extension of the strip 93, 94 andprovided with side folds 99 (Figure 9) to secure the desired rigidity. If further rigidity is desired than can be provided by the flaps 99, the sheet 35 may be r'eenforced by a rigid sheet of heavier stock glued thereto. The ends of the sections 93 and 95 adjacent the fold line 95a are punched to receivethe rings 86, and the ends of the sections 93 and 94 are creased, as at 93c. and 94a, to form a stub 90 which is secured in any suitable manner as by gluing, or by a rivet 91, to the outer end of the cover 82. The section 94 is provided with a fold line 08 which is creased so that when the binder is closed the section automatically folds upwardly and inwardly similar to the forms shown in Figures 1 and 6. As in the forms of the invention set forth above, the tension sheet 93 acts at the point 91 and against the rings 86 to hold the upper cover 8| in a position generally in the same plane as the lower rigid sheet 95, whereby the sheets 89 can be displayed one above the other in generally coplanar relation.

A binder of this type can be manufactured very inexpensively, actually at a cost only slightly greater than the ordinary ring binder, yet, by virtue of the panels 93, 94, and 95 and their arrangement as described above, the binder may be quickly opened into display position and as quickly folded to closed position without the manipulation of any struts, snaps, hooks or other objectionable accessories.

Figure 10 illustrates a binder I similar to that shown in Figure '7 and just described. In Figure 10, the binder is also of inexpensive construction, embodying cardboard covers IM and I02 connected together by a fabric section I03 that is flexible. In this form of the invention, the sheet binding means I05 is of the mechanical type, sometimes known as permanent binding inasmuch as when completed, the binding means is not separable to permit removing or replacing sheets, and is of the type known in the art as Cercla binding. This binding consists of a joint or connecting section I01 formed of sheet metal and provided with rings or arches I08 preferably formed integrally with the section I07. The rings or arches I08 are inserted through the punched openings in the sheets to be bound, and then the ends I09 of the parts I08 are disposed against the connecting section or joint I07. Then the portion IIO of the connecting section IN is crimped or pressed downwardly to clamp the ends I 09 and lock them in place. The connecting section or joint I01 thus connects all of the rings I08 together. It is not necessary, of course, to have all of the rings I08 of any one binder connected together, sincethe binding means may, for example, be divided into two or more sections, especially in the smaller binders where it is not necessary to have a set of continuous uniformly spaced binding rings or arches.

The binder I00 has a supporting easel II5 that includes interconnected panels or sheets H0, H1, and II 8, the latter having 'an inwardly creased fold line H9, and preferably the sections H6 and Ill are connected integrally together at a fold line I 2I adjacent which the sheets H6 and II! are punched, preferably simultaneously with the sheets I22 forming the pages of the binder. A sheet I23, which is to be glued to the cover IOI as will be described below, is also punched and bound by the rings I08 at the same time as the panels II 6 and II! and the sheets I22. In the more inexpensive forms of the binder, such as the one illustrated in Figure 10, the sheets or panels H0, H1 and H8 are formed in one strip, as illustrated, having their ends brought together to form a stub I24 and glued or riveted to the outer edge of the cover I02.

In this form of the invention the rigid panel section, indicated at I30 and which cooperates with the cover I02 and the other sheets H6 and II8 to complete the easel support II5, includes a sheet I3I of somewhat heavier stock, depending upon the size and weight of the binder, than the panel II I. The sheet I3I is glued to the panel III after the sheets IIB, II 1, and I23 and the leaves I22 are punched and bound by the binding means I05. The manner of mounting the rigid reenforcing panel I3I will now be described.

Referring now to Figure 12, this view shows the sheets I22, the gluing sheet I23, and the easel panels IIS and I I1 punched to provide apertures I35 to receive the binding means I05. The binding is then applied by inserting the rings I08 through the openings I35, and then crimping the joint I01 to fasten the rings in position. Then the joint I0! is swung over to a position over the easel sheet I IT, as shown in Figure 13. Next, the reenforcing panel I3I, which, as best shown in Figure 16, is provided with punched openings I35a, each of which has a slot I36 leading out to the adjacent edge of the sheet I3 I, is run through a gluing machine to apply glue to one side thereof, and then the panel I3I is applied with the glue side toward the panel Ill and firmly pressed thereagainst, the slots I 38 permitting the rings I08 to be forced into the slots I350. at the inner edge of the sheet I3! as best shown in Figures 14 and 15. Lastly, glue is spread on the back side of the gluing panel I23 and the latter fastened to the cover IOI, as indicated in Figure 14, and at this time the edges forming the stub I24 of the easel are riveted or glued to the outer edge of the upper cover I02. This completes the binder, and the same may be set up in display position shown in Figure or folded to a position similar to that shown in Figure 3. It Will be understood that the thicknesses of the various parts are somewhat exaggerated in Figures 12 to in order to illustrate the construction, and that actually the sheet I3I is glued to and lies closely against and reenforces the panel II'I.

One of the advantages of the construction shown in Figures 10 to 15 is that the joint I01 of the binding means I05 is, after the binder has been completed, entirely hidden from view and entirely removed from any position in which any of the sheets I22 might be caught thereon. The leaves I22 turn freely at all times, whether the binder is opened asan ordinary book or set up for display, as in Figure 10, with the leaves turned from one position to another to provide a doublepage spread.

The feature of gluing the reenforcing panel, as at I3I, to the easel panel II! provides an arrangement which is particularly advantageous in that the desired rigidity for the member I30 of the easel may be secured without varying the thickness of the stock from which the panels H5, H6, and II! are formed, since to vary rigidity of the member I30, it is necessary only to supply reenforcing sheets I3I of different thicknesses.

While I have shown and described above the preferred means in which the principles of the present inventionhave been embodied for the purpose of illustrating the same, it is to be understood that my invention is not to be limited to the specific details shown and described above, but that, in fact, widely'difierent means may be employed in the practice of the broader aspects of my invention.

A display binder comprising a pair of rigid cover members, a section connecting adjacent edges of the cover members, a plurality of sheets having perforations along one edge, loose leaf metal secured rigidly to one of said cover members adjacent its inner edge and having arch members extending through the perforations in said sheets and permitting the latter to be turned over progressively from one side of the binder to the other when the binder is opened, a foldable easel normally folded between said sheets and the other cover member when the binder is closed and comprising three panels adapted when extended to form a triangle, one panel being constructed so as to tend normally to fold inwardly and connecting the other two panels adjacent their outer edges, said other two panels being perforated adjacent their inner edges to receive the binding means of said loose leaf metal and movable relative thereto from one side of the loose leaf metal to the other side thereof adjacent the inner edge of said one cover member when the latter is swung backwardly about said section so as to bear against the inner edge of said other cover member, and means securing the outer edge of the outer of said two panels to the outer edge of said other cover member whereby said outer easel panel acts in tension to hold said one cover member and the inner of said two easel panels in substantially coplanar relation, thereby providing for the simultaneous display of two sheets to present a double page spread.

16. A display binder comprising, in combination, substantially rigid front and back covers, a section interconnecting adjacent edges of said covers, a substantially rigid panel hingedly connected at its inner edge to one of said covers along said adjacent edge thereof, a flexible connector interconnecting the other of said covers and said rigid panel for limiting movement apart thereof through a predetermined angle, and means for limiting movement apart of said one cover and said panel through a predetermined angle.

17. A display binder comprising, in combination, substantially rigid front and back covers, a

section interconnecting adjacent edges of said covers in spaced apart relation sufficiently to permit said covers to lie substantially parallel to each other when the binder is filled and closed, a substantially rigid panel hingedly connected at its inner edge to one of said covers along said adjacent edge thereof, a connector interconnecting the other of said covers and said rigid panel for limiting movement apart thereof through a predetermined angle, and means for limiting movement apart of said one cover and said panel through a predetermined angle.

18. A display binder comprising, in combina-. tion, substantially rigid front and back covers, a section interconnecting adjacent edges of said covers in spaced apart relation suflioiently to permit said covers to lie substantially parallel to each other whenthe binder is filled and closed, a substantially rigid panel hingedly connected at its inner edge to one of said covers along said adjacent edge thereof, means including a plurality of hingedly connected members hingedly connected to the other of said covers and said rigid panel for limiting movement apart thereof through a predetermined angle and adapted to be folded therebetween when the binder is closed, and means for limiting movement apart of said one cover and said panel so that one forms substantially an extension of the other when the binder is open.
